1 Most of the other different groups of organic compounds that are 



2 present there are in the part per billion level and that is before it 



3 comes out of the pipe. You are looking at these 10% 10^ dispersion 



4 ratios in that first 1,000 or 2,000 feet or so. 



5 But that is the concentrations you are starting at as far as the 



6 organics that are associated with the oil, so as I say, the BXT complex 



7 which, probably as a single group, are the highest in the low part per 



8 million range. 



9 All of the individual compounds that you potentially track--the 



10 naptholene and some of those other things--are in the mid to low part 



11 per billion range as individual components. 



12 DR. AURAND: Would it be reasonable to say: If there were to be 



13 production, the mechanism of discharge would have to be carefully 



14 examined? Do you want to say something like that? 



15 DR. RAY: Pat had a comment to me here a minute ago. She was just 



16 saying that with some of the larvae and stuff that tended to congregate 



17 near the surface level, that probably if you just were shunting down 10 



18 meters, you know, that alone, by the time the produced water--if it came 



19 back to the surface, by the time it gets there, it probably would have 



20 gone through a dilution. 



21 MS. HUGHES: The question was: What is the surface discharge? 



22 Does industry consider a surface discharge to be anywhere from the 



23 surface to below 10 meters? 



24 I was thinking of the surface waters and hydrocarbons with regard 



25 to lobster larvae. 



26 DR. RAY: Your point, then-- 



27 MS. HUGHES: They are in the yery upper few, less than 5 meters, 



28 of water. 



29 DR. GRASSLE: I think it's safe to see a water column effect in an 



30 oil spill situation, even when there are larvae out there. 



31 DR. BUTMAN: I just did a rough calculation. If you take that 



32 2,000 barrels a day at 48 parts per million, that's about 1 liter of oil 



33 per day in terms of total volume. 



34 DR. AURAND: At a volume of 2,000 barrels?
